Abstract: :
Purpose:To evaluate the imaging characteristics of selectedchoroidal disease using the SLO OCT.Methods:A retrospective review was made of cases of choroidaldisease imaged using the SLO–OCT (OCT Ophthalmoscope,University of Kent, Canterbury; UK for OTI, Toronto, Canada).Longitudinal and coronal scans were analyzed to determine ifuseful information could be derived from these images.Results:Between April and November 2003, eight patients withthe following choroidal pathologies were seen: choroidal rupture,choroiditis, polypoidal choroidopathy, choroidal vasculopathy,choroidal granuloma. The extent of damage to the choroid andchanges in the choroidal bed were evident from the scans examined.There seemed to be an improved visualization of the choroidcompared to the OCT3, and this may be attributed to the mannerin which images are acquired. Due to en face (transverse) scanning,the OCT image is continuous along the line of the raster, asopposed to the images generated by the OCT 3 which utilizesaxial scanning.Conclusions:En face imaging results in superior resolution inboth longitudinal and coronal scans, which allows excellentvisualization of changes in choroidal lesions.
